I have mcleod RST TWIN DISC CLUTCH, new in the box, did not even open the box yet. I got the clutch, then after couple of days i left the country and I never used it. now I have different plans. thats why I want to sell it ... It can handle up to 800 rwhp ( that what the guy at mcleod told me and he said you can upgrade it to RXT any time you want, it can handle over 1000 hp ..
